Alprostadil EP Impurity F CAS 21003-46-3 chemical structure

Description

CATO manufactures Alprostadil EP Impurity F under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

CATO supplies Alprostadil EP Impurity F (CAS 21003-46-3), a pharmacopoeial impurity reference standard (molecular formula C20H34O5, MW 354.48 g/mol) used for the identification and quantification of trace impurities in APIs.

Alprostadil EP Impurity F (C20H34O5) contains a steroid core, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
